When you say 'same package configuration', do you mean you just want the
same set of packages (latest versions), or that you want to specify both
packages and version numbers?
I've been investigating doing both. For the former, I've written a little
tool here:
http://www.openfusion.com.au/labs/xsync/
that lets you assert what packages and services should and should not be
installed and/or running e.g.
# Ensure some packages are removed
touch /etc/xsync/rpm-remove.d/{nfs,nfslock,portmap,ypbind}
# Ensure some other packages are installed, up to date, and running
touch /etc/xsync/yum-install.d/{httpd,mod_perl,openssh-server}
touch /etc/xsync/chkconfig-on.d/{httpd,sshd}
# Check those changes look okay
xsync -n
# Update the system
xsync
Typically you do this somewhere central, and then push out the (one or
more) /etc/xsync trees to your target boxes.
Cheers,
Gavin
